Title: Improvements relating to tool changing devices for machine tools
IPC: B23Q3/155
Filed: 1966-09-09
Abstract: 1,114,087. Tool-changing. HEIDENREICH & HARBECK. 9 Sept., 1966 [22 Sept., 1965], No. 40317/66. Heading B3T. A lathe comprises an indexable tool-holder store 16 and a slide 5 carrying a tool-post 11, the store being able to pass over the post in its end position. The cutting and tool-changing movements are controlled by camstrips 8 co-operating with switches 9. The saddle 5 carries a cross-slide 10 carrying a tool-holder W 1  on the tool-post 11. The store 16 is rotated on an adjustably-mounted base 13 through worm gearing by a motor 15 which also drives a cam drum in a casing 13b. In operation, the saddle 5 is retracted to cause a plunger 34, Fig. 4, on the post 11 to engage a stop 36 on the base 13. Continued movement of the saddle causes teeth 33 in the plunger to rotate a pinion 32 on a nut 30, Fig. 3, to release a locking bolt 24, 25. A lever 37 on the post is then engaged by the plunger and is moved to advance a pin 39 which engages the holder W 1  and causes teeth 22 thereon to be disengaged from teeth 21 on the post. At the same time, wedges 44 lift the holder on to supports 17 on the store where it is secured by plungers 45. The store is indexed to any position where it is located by a spring-pressed ball 48. Advance of the saddle causes the new holder to be taken up and locked, the plunger 34 being rendered effective by a retaining catch 35 operated mechanically or by a solenoid. Alternatively, the plunger 34 may be mounted on the base 13. In modifications, the store is moved instead of the saddle, or each may be moved, or the store may be moved linearly. The holders may be clamped hydraulically or electrically.

Abstract: 1,224,080. Acid regeneration by ion exchange. MULTI-MINERALS Ltd. 28 Aug., 1968 [13 Sept., 1967], No. 41048/68. Heading C1A. Cations are removed from an acidic solution by contacting it with an ion exchange resin in the hydrogen form, the contacting taking place while substantially all those cations which have more than one oxidation state are maintained in an oxidation state lower than their highest, and under conditions where this lower state is maintained. The acidic solution may be treated with a reducing agent, e.g. metallic Fe, SO 2 , metallic Al, or H 2 S, before contact with the resin, and the solution maintained in a non-oxidizing medium prior to and during the resin contact step. The acidic solution may be contacted with dry resin, and the product contacted with more resin, the acid then being eluted out. The cations may comprise iron. The resin may be backwashed, and regenerated preferably with a regenerant solution comprising sulphurous acid and a carbonyl compound, e.g. acetone, acetaldehyde, crotonaldehyde, cyclohexone, furfuraldehyde, isobutyaldehyde, or methyl ethyl ketone. The regenerant may be treated to recover SO 2  and the carbonyl compound. The recovery of SO 2  may cause salts, e.g. sulphites and oxides to precipitate, and these may be recovered. The acidic solution, after contact with the resin, may be heated to recover rare earth compounds, normally as a gel, by heating to 88-95 C. The acidic solution may be neutralized, before contact with the resin, either with a basic material, or by contact with a resin in the sodium form. The solid material is filtered off, and the iron in the solution reduced, and the solution then contacted with the resin.

Filed: 1964-10-09
Abstract: 1,083,497. Boring earth &c. INSTITUT FRANCAIS DU PETROLE DES CARBURANTS ET LUBRIFIANTS. Oct. 9, 1964 [Oct. 10, 1963], No: 41347/64. Heading E1F. During drilling of an underwater borehole from a floating body N by means of a flexible tube 1 supporting the drill and bit 2, 3 at one end and attached at B to the body at the other end, the bit pressure is maintained substantially constant in spite of vertical movement of the body due to waves by passing the tube over a pulley 4 mounted with a pulley 8 on a member 13 movable by the piston of a ram 14 along a slide 12 fixed to the body, and by passing a guide line 6 extending from an anchor 7 adjacent the borehole to a position 11 fixed on the body over the pulley 8 and through guides 8, 9. The force on the piston is maintained substantially constant by connecting the ram to a large reservoir 15. Vertical movement of the body from tides is compensated by adjustment of the lengths of the tube and the line, and the tube is paid out at intervals to permit the hole to be extended. The tube, which is gripped between pads P on chains C 1 , C 2  of a hauling device 5, forms a passage for drilling fluid and carries the electric cables for the drill. In a modification in which the variations in drill pressure are smaller, the upper guide roller 9 is more remote from the slide 12 than the lower roller 8.

Title: Stack mechanism for a data processor
IPC: G06F12/12
Filed: 1973-09-05
Abstract: 1405700 Data processing INTERNATIONAL BUSINESS MACHINES CORP 5 Sept 1973 [20 Oct 1972] 41701/73 Heading G4A A data processing system comprises a high speed stack store 2 (Fig. 1) operating in a last in/ first out mode and a slower speed store 3 to which all overflow entries in the stack are rolled out only when the stack is full and a read in operation is requested and from which they are rolled back only when the stack is empty and a read out operation is requested. A further backup register 15 may be provided to store the last entry transferred to the slower speed store. Read in to the stack.-The value of a stack top pointer STP (Fig. 2) representing the address at which data is to be inserted is fed via AND gates 23 and OR gate 22 to an address register for the high speed store, the data being read from register 12 into the stack and the stack top pointer being incremented by one. Read out from the stack.-In a similar manner the stack top pointer is used to address the stack, the data being read out on bus 20 to either register 9 or 10 for transfer to an arithmetic unit 11, register 13 or via gates 16b for entry into a non stack area of the slower store 3. The stack top pointer is decremented by 1. Roll in routine.-When the values of the stack top pointer STP and a stack bottom pointer SBP are identical, at a subsequent read out operation, AND gate 103 is enabled to set an X bit latch 101 so that at the next read out operation the data from the back up register 15 is used and fed via AND gates to either the A or B registers, a roll in routine being simultaneously called up. This results in a store 145 supplying a branch address to control store 30 to access the first micro programme control word in the routine. The number of entries to be transferred is then entered into register 142. A slow stack pointer SSP is decremented and used to access the stack area 4 of slow speed store 3 to read data on bus 17 to the stack 2. The pointer SBP is also decremented and fed via AND gate 24 to OR gate 22 to address the stack. For each stored entry the contents of register 142 are decremented and compared with zero in a comparator 143, the routine terminating at comparison after one additional entry has been stored in register 15. Roll out routine.-When comparator 107 detects during a read in operation that SBP equals STP + 1, provided latch 101 is not set, the data is entered in the back up register 15 and a roll out routine is called up. This results in store 145 addressing the control store 30 to access the first micro programme control word of the routine. The stack bottom pointer is fed via AND gate 24 to address the store 2 and the read out data is transferred with the stack bottom pointer SBP being incremented each time to store 4 for read in at an address specified by the pointer SSP which is also incremented. This process is repeated until, as in the roll in routine, the register 142 is decremented to zero.

Examples are given in which 2,4,6-triphenylbenzene diazonium fluoroborate, pyrene-3-diazonium chloride, and anthracene-9-diazonium chloride, and anthracene-9-diazonium fluoroborate are coupled with b -naphthol.ALSO:The invention comprises 2, 4, 6-triphenylbenzene diazonium salts, anthracene-9-diazonium salts, and double salts thereof. The invention also comprises diazonium salts of primary amines obtained by diazotizing the amine or salt thereof with NO in the presence of an anhydrous organic solvent, where necessary in the presence of a further oxidizing agent, the product obtained being converted, where necessary, into the desired diazonium salt with the aid of a Lewis acid.  In one method, NO, protected from atmospheric oxygen, is reacted with the amine in solution in an organic solvent, and the precipitated diazonium hyponitrite may then be converted into another diazonium salt with an appropriate acid.  Alternatively, NO, protected from atmospheric oxygen, is reacted with a salt of the amine in suspension in an anhydrous organic solvent to give the corresponding diazonium salt. Specified further oxidizing agents are Na or K ferricyanides, oxidizing metallic oxides such as PbO2, MnO2, HgO, Ag2O, and V2O5, and the nitrous vapours produced in situ by the introduction of a moderate quantity of O2 into the solution, which oxidizes a part of the NO present. Specified solvents are ethers and hydrocarbons of the benzene series.  Specified Lewis acids are HCl, H2SO4 and HBF4.  Alternatively the acid may be used in the presence of one of its salts to form the double diazonium salt.  Examples are given for the preparation of 2,4,6-triphenylbenzene diazonium fluoroborate, pyrene-3-diazonium chloride and anthracene-9-diazonium salts, including a double salt with ZnCl2.  The diazonium salts may be coupled with a coupling agent to form dyes (see Division C4).
